Analysis of Probability States and Preventive Maintenance Assessment of HF Power Converter for Induction Heating Technologies

The paper considers the application of a probability analysis so as to define the maintenance time and the operation of electronic converters. Models with probability states that are typical for this type of devices are presented. Those states could be summarized as: operability, repair, preventive maintenance, protection, redundancy and failure. The proposed models reflect the probability that a specific electronic device is in one of the above states at a specific moment of time. Maintenance time is determined on the basis of those probabilities and the methodology for defining maintenance time and interval reliability by the end of the period.
